What is it? The VisionCare Ophthalmic Technologies Implantable Miniature Telescope TM (IMT) is a system to magnify objects to improve vision in patients with end-stage, age-related macular degeneration (AMD). The IMT is surgically implanted in one eye only and is available in two models. One with 2.2 times magnification and the other with 2.7 times magnification.
How does it work? The IMT magnifies images and projects them onto a part of the retina that is healthy and can still see images. It does not cure macular degeneration.
When is it used? The IMT is intended to improve vision in patients 75 years of age or older with stable, severe to profound vision impairment caused by end-stage age-related macular degeneration. It is indicated for patients with geographic atrophy or disciform scarring of the fovea, a visually significant cataract, and who achieve at least a 5-letter improvement on the visual acuity chart using a trial external telescope.
What will it accomplish? The IMT may improve distance and near vision in people who have lost central vision because of end-stage AMD.
